At the forefront of developing Li-S cell and battery technology

Our history

OXIS has developed its unique technology around sulfur based cathode materials, highly stable electrolyte systems and anode made of Lithium metal and intercalation materials.

We are based on the Culham Science Centre in Oxfordshire where the original Lithium-Ion batteries were first developed and prototyped. We have well equipped laboratories with state of the art equipment and large dry room facilities.

What we do

OXIS and its research partners are focusing on the development of the world leading Li-S chemistry that can be used in many battery applications. Mass production of the cells is handled by our manufacturing plants in Brazil and in the UK.

OXIS is a member of RECHARGE, a non profit organization founded to promote the value of rechargeable batteries and represent the interests of all its members in the chain of battery life.

OXIS has completed full registration with the US government under the SAM.Gov Scheme and as such we are able to let our customers and government procurement officers know that you are registered as the US Federal Contractor Registration Verified Vendor

OXIS Patent Portfolio

OXIS has 39 patent families with 165 patents granted and 101 pending. The patents cover electrolyte systems for lithium sulfur cells, methods of lithium sulfur cell construction and also positive and negative electrodes. The patent portfolio is rapidly growing and it reflects the success of our research and development program.

Published patent families include:

An electrolyte for batteries with a metal lithium electrode

Electrolyte for lithium-sulfur batteries and lithium sulfur batteries using the same

Connecting contact leads to lithium based electrodes

Method of charging lithium sulfur cell

A Method of cycling a lithium-sulphur cell

Our strategy

Our strategy is to work with world class partners to develop the chemistry into a product that can be used in a range of applications and build cells on our pilot production line to prove its performance. OXIS will then licence this Li-S technology to its manufacturing partners for mass production to allow us to continue to develop the chemistry further and revolutionise the energy market.
